 1 | # Objective-C Encoding Parser
 2 | 
 3 | This library is a simple parser for Objective-C [type encoding](https://developer.apple.com/library/archive/documentation/Cocoa/Conceptual/ObjCRuntimeGuide/Articles/ocrtTypeEncodings.html) with a focus on cross-platform.
 4 | 
 5 | See [parser.h](./parser.h) for the provided APIs and [run-test.c](./run-test.c) to learn how this library works in action.
 6 | 
 7 | ## Features
 8 | 
 9 | * Simple and intuitive APIs, ready for use without reading any documents.
10 | * Zero-dependency and platform-agnostic, tested in macOS, Linux and Windows, easy to integrate with your various analysis facilities.
11 | * Full support of the type encoding syntax (including struct, union), and able to get the related information of the type (like name, size and alignment).
12 | * Error tolerance for ill-formed encoding strings, the library parses inputs in its best effort.
13 | * Built-in dump function to print the human-readable string describing the type.
14 | 
15 | ## Building
16 | 
17 | ### Make
18 | 
19 | ```
20 | git clone https://github.com/unixzii/objc-encodingparser.git
21 | cd objc-encodingparser
22 | make
23 | ```
24 | 
25 | This will generate both the static library `libocep.a` and a `run-test` program.
26 | 
27 | ### Xcode / Visual Studio
28 | 
29 | The project (solution) both contains two targets: `libocep` and `RunTest`. Once build is succeeded, you can retrieve the products from your IDE's build directory.
30 | 
31 | ## Type Node Explained
32 | 
33 | `ocep_type_node_t` is the core structure of this library, you parse an encoding string and get the result with that type. It's like an n-ary tree and each node has a parent pointer, a child pointer and a sibling pointer. An example is shown as the below figure:
34 | 
35 | ![Example Node](./misc/node_structure.png)
36 | 
37 | You can use `ocep_type_node_traverse` function to visit all the children (include itself) of a given node in a DFS-fashion traverse.
38 | 
39 | ## Limitations
40 | 
41 | * Bit fields are currently not supported (since it's rare in Objective-C code), submit an issue if you see this important.
42 | * Type size is now calculated in the compact layout (eg. `"{?=c^vc}"` will get a size of 16 while actually it's 24).
